Check your coolant reserve tank and fill it if needed. If the coolant is fine try flushing the heater core, follow ChrisFix's instructions in the vid linked below. How to Flush Heater Core Safely with garden hose As a side question: Were there any loose wires that could have been caught near the fan when you replaced it? They'll make a buzz noise if they're touching the fan blades.

Same answer as before.

It is very possible that the heater core is stopped up. When the engine is warmed up with the heater on test the two hoses going to the fire pasenger compartment from the engine both should be hot. If not hot problem is most likely heater core clogged up.

Sounds like a problem with your Head/park light switch. Could be plumb wore out on a '91.

No, it would still start, just might have some air in your coolant which could cause overheating after it warms up. Check that it is getting fuel and spark. If it overheated badly before, check compression in the cylinders, looking for a blown head gasket.

If in fact they are doing it sometimes, but not all the time, this is indicating worn out belts, and they need replacement. Belts can look good, but can slip and squeal when they get hard and brittle. I, too, have had that experience with my Hondas. If the belts did it all the time, you would look for a defect in of the components that the belt is driving. ( Water pump, a/c compressor, idler pulley, power steering pump, alternator, etc.) God bless your efforts.

Should be a black hose from the inlet manifold to the rocker cover the p.c.v should be at the end of the hose.

try each different key position

It isn't too hard to get it started, but your steering will still be locked without a key. You can unscrew the electrical section of the ignition switch off the mechanical section and turn it with a screwdriver, then to be able to turn the wheel you remove the mechanical section, usually with a hammer and chisel, since it is held on with anti-theft breakaway bolts. A locksmith might be easier.

Remove the thermostat and run the engine at idle until it starts to overheat. If it does then the radiator may have clogged veins and needs replacing.

are you sure you the adjustment to it is correct the button in the end of the switch has to be fully depressed to deactivate the circuit

I don't believe that the 1991 Accord DX had a Honda accessory alarm option, but regardless, factory or aftermarket, it was wasn't installed at the factory, it was installed at the dealer or an aftermarket store. Just remove it, and reattach any cut wires.

Then, do the usual checks for spark at the plugs, and fuel at the rail. Hope this helps.

CHECK TO SEE IF YOU DIDN'T PUSH THE PINS IN THE FUUE BOX TO DEEP THAT THE RELAY IS NOT MAKEN CONTACT..

main relay.there is a relay underneath the dash thy are culprit of no starts on honda accords its gray in color

Relay or fuse?

The Honda system uses a coil that mounts inside the dist, right ?If you can check voltage output at the coil tower with the cap off you can find out if the coil is firing. If it is, then yes the rotor could be the problem. The voltage has to go thru the cap to the center of the rotor then to each plug terminal. The spark can jump thru the rotor and ground thru the dist shaft.

The o2 sensors because the car may have more than one, are located before the catalic converter, they look like spark plugs with 3 or more cables running from the top, scan the car to check for other codes.
